Brilio.net - Chance is one of the basic concepts in mathematics related to the possibility of an event occurring. This concept is very useful to help you understand the probability or possibility of an event occurring in an experiment. Chance is not only applied in the world of mathematics, but also in everyday life, such as when you roll a dice, pull a marble from a bag, or choose one of several options.
At the 6th grade level, the concept of probability is introduced in a simple way to help students understand how interesting this concept is. Through practical and easy-to-understand problems, students can learn how to calculate the probability of various random events. Some examples of activities used to learn about probability include flipping a coin, drawing a ball from a bag, or choosing a number on a die.
Here are examples of probability questions accompanied by complete discussions, reported by brilio.net from various sources, Tuesday (4/2). These questions are designed to help 6th grade elementary school students understand how to calculate probability easily and enjoyably. By studying these questions, it is hoped that students can be more confident in facing various mathematical problems related to probability.
Example of class 6 probability questions

1. Question:
There is a bag containing 5 red balls and 3 blue balls. If one ball is drawn at random, what is the probability that the ball drawn is red?
Discussion: Number of balls in the bag = 5 red balls + 3 blue balls = 8 balls in total.
Probability of drawing a red ball = Number of red balls / Total number of balls = 5 / 8
Answer: 5/8
2. Question:
On a die with 6 sides, what is the probability of getting the number 4?
Discussion: The number of sides of the dice = 6 (numbers 1, 2, 3, 4, 5, 6).
The probability of getting the number 4 = Number of numbers 4 / Total number of sides = 1 / 6
Answer: 1 / 6
3. Question:
In a box there are 3 red marbles, 2 blue marbles, and 1 green marble. If one marble is drawn at random, what is the probability that it is a green marble?
Discussion: Total number of marbles = 3 red + 2 blue + 1 green = 6 marbles.
Probability of taking a green marble = Number of green marbles / Total number of marbles = 1 / 6
Answer: 1 / 6
4. Question:
In a class there are 15 male students and 10 female students. If one student is chosen at random, what is the probability that the student chosen is a girl?
Discussion: Total number of students = 15 boys + 10 girls = 25 students.
Probability of selecting a female student = Number of female students / Total number of students = 10 / 25 = 2 / 5
Answer: 2 / 5
5. Question:
If a coin is tossed, what is the probability of getting heads?
Discussion: A coin has two sides: a picture and a number.
Probability of getting a picture = Number of picture sides / Number of coin sides = 1 / 2
Answer: 1 / 2
6. Question:
In a bag there are 4 green balls, 2 yellow balls, and 3 red balls. If one ball is drawn at random, what is the probability that the ball drawn is yellow?
Discussion: Total number of balls = 4 green + 2 yellow + 3 red = 9 balls.
Probability of drawing a yellow ball = Number of yellow balls / Total number of balls = 2 / 9
Answer: 2 / 9
7. Question:
On a dice consisting of numbers 1 through 6, what is the probability of getting an odd number?
Discussion: The odd numbers on the dice are 1, 3, and 5. So, there are 3 odd numbers.
The probability of getting an odd number = Number of odd numbers / Total number of sides = 3 / 6 =1 / 2
Answer: 1 / 2
